In the video tutorial it mentions entering your name or your publisher's name along with ISBN. Is it possible to have my publisher market through B&N and I use the publisher and ISBN on Amazon. They publish for Amazon but not kindle, only paperback.

You don't need an ISBN for eBooks on Amazon. They use their own ASIN for book identification. If you DO choose to use an ISBN, it cannot be from a print copy. Each format (print, kindle, ePub, pdf, etc) must have a unique number if you choose to use an ISBN. But why spend the money on Amazon when it won't be used?

One question--do you have e-rights for your book? Just because your publisher only does hardcopies doesn't mean that they don't control e-rights.

Check your contract. Most publishers make authors sign over pretty much all rights in sight. If you published on Kindle by yourself and they held the rights, they would be peeved. They could (at least theoretically) sue you for your Kindle royalties or stop publishing your paperbacks.

Of course if you only granted them hardcopy rights, go for it. And as others have said, don't worry about an ISBN. Leave that blank.
